BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 223,283, dated January 6, 1880.

' Appnmutn inea June 11,1879.

To all whom t may concern Be it known that I, NrooLAY FRITZNEE, of Berlin, in the Kingdom of Prussia and German Empire, have invented a new and useful Improvement in BottleStop1i ers, of which the following is a specification.

The invention relates to that class of stoppers which, composed of a common cork and ofthe mechanical device, are used on bottles for perfumes, fragrant essences, can de cologne, and similar fluids, and which are constructed in such manner as to permit the fluid to be discharged in small quantities-if de'v sired, in drops.

The object of my invention is to better se cure the mechanical device to the cork, to increase the certainty that the fluid shall commence to be delivered promptly through a very limited opening, and by reducing the surface wetted by the iiuid beyond the stopping-point to cconomize the consumption in delivering` small quantities.

ln the accompanying; drawings, in which similar letters of reference indicate like parts, Figure l is an axial section of my improved stopper. Fig. 2 is an elevation. Fig. 3 is a cross-section of the screw-cap on the line A B of Fig. l. Fig. 4L is an axial section of such stopper simplified in some respect.

Similar letters of reference indicate corresponding parts in all the figures.

The cork-tube a, fastened to the cork k of the bottle by expanding the inner end of the tube a, as indicated by a', after it is freely inserted, is provided with the shield o and the screwthreaded part (l. The axial hole e of the cork-tube c narrows toward the top of the screw part d. rlhe cap b, iitting with its fe male screw to the screw d, is provided in its center with a cone, n, and perforated by a'single small outlethole, p, which, commencing at the side of the cone a, passes through the body of the cap bin an oblique direction, and opens or terminates in the center of the top of the cap b.

When the cap b is screwed down the cone n is forced into the opening ofthe hole caga-inst its upper sharp edge, shutting off any discharge ofthe contents of the bottle. A little back turning of the cap I) allows the fluid to be discharged in single drops, and giving to jecting from the shield c.

the cap b two or three turns more will open the passage to its full extent, so that the lluid may iiow out in a small stream in proportion to the openings e and p.

Knurled rims o h facilitate the manipulating of the cap b.

To avoid the possibility of losing the cap b by unscrewing it entirely from the piece d, the former is provided on its lower extremity with an annular upset, m, playing in a ring, g, pro- The upper edge, l, of this ring g is turned over to the inside, so as to lock the upset m if the cap b is screwed loose for two or three turns, and prevents, by this means, the cap b from being lost. This arrangement ofthe stopper is represented in Figs. l, 2, 3, while Fig. 4 shows itin its simpler form. ,t Y

I prefer to cast the parts a and I) of the stop per, say, in tin, britannia, or other metal, or in' any other suitable material, so that all the work required after their eastin g is the insertion and the fastening of the part a to the cork 7c by the expanding or turning outward of the lower end of the tube a, as shown, and the spinning over of the edge l after the cap b is screwed on the screw part d.

The locking ofthe mechanical device to the cork by the turning outward of the inner end of the tube contributes to the durability and mechanical perfection of the device.

The tapering form of the hole e gives an ample passage at the inner end of the tube, so that the fluid can readily enter and the air escape so soon as the bottle is inverted, requiring but a small orifice at the outer end, which is stopped by the concu. Providing a single hole, p, reduces the surface which is to be wetted by the fluid, and reduces the quantity of iiuid which is required to pass the stopped point a before it will begin to escape at the outer opening. This latter quality is of special importance in the use of fluids which are volatile, so that all the material left on the surfaceswill evaporate and be lost before the next use of the device, and also in the use of iuids which, like some of the oils, oxidize and change by contact with the air.

Ordinary devices of this kind have two or more holes. l have discovered that one will serve better.
